2017 Mazda RX 7
2017 Mazda RX-7 very modern sports car. All drivers expect a lot from this vehicle. http://www.2016bestcars2017.com/2017-mazda-rx-7-price-and-redesign/ -~-~~-~~~-~~-~- Please watch: "2018 Subaru XV exterior, drive, factory, engine" https://www.youtube.com/watch?v=Q0sCvNo6K9E -~-~~-~~~-~~-~-





🔰 3&4 ROTOR, MAZDA RX7 FD3S
The third generation of the RX-7, FD (with FD3S for Japan and JM1FD for the USA VIN), featured an updated body design. The 13B-REW was the first-ever mass-produced sequential twin-turbocharger system to export from Japan, Boosting power to 255 PS (188 kW; 252 hp) in 1993 and finally 280 PS (206 kW; 276 hp) by the time production ended in Japan in 2002. In Japan, sales were affected by the fact that this series RX-7 no longer complied with Japanese Government dimension regulations, and Japanese buyers were liable for yearly taxes for driving a wider car compared to previous generations. As the RX-7 was now considered an upper-level luxury sportscar due to the increased width dimensions, Mazda offered two smaller sports cars, the Eunos Roadster, and the Eunos Presso hatchback. The sequential twin turbocharged system, introduced on this series in 1992, was a very complex piece of engineering, developed with the aid of Hitachi and previously used on the exclusive to Japan Cosmo series (JC Cosmo=90–95). The system was composed of two turbochargers, one to provide Boost at low RPM. The second unit was on standby until the upper half of the rpm range during full throttle acceleration. The first turbocharger provided 10 psi (0.7 bar) of Boost from 1800 rpm, and the second turbocharger was activated at 4000 rpm to maintain 10 psi (0.7 bar) until redline. The changeover process occurred at 4500 rpm, with a momentary dip in pressure to 8 psi (0.6 bar), and provided semi-linear acceleration and a wide torque curve the throughout the entire rev range under "normal operation". However, under performance driving the changeover process produced a significant increase in power and forced technical drivers to adjust their driving style to anticipate and mitigate any over-steer during cornering. Many owners modified their turbo control systems into a parallel system by removing the Exhaust manifold turbo Control Valve and the turbo coupling "y-pipe" Charge Control Actuator and valve in order to remove the changeover process and to simplify the control system for reliability. turbo lag was greatly increased below 4500 rpm, but smooth and linear Boost could be obtained. The stock turbo control system used 4 control solenoids, 4 actuators, both a vacuum and pressure chamber, and several feet of preformed vacuum/pressure hoses all of which were prone to failure in part to complexity and the inherent high temperatures of the rotary engine. Australia had a special high-performance version of the RX-7 in 1995, named the RX-7 SP. This model was developed to achieve homologation for racing in the Australian GT Production Car Series and the Eastern Creek 12 Hour production car race. An initial run of 25 originals were made, and later an extra 10 were built by Mazda due to demand. The RX-7 SP produced 204 kW (274 hp) and 357 N·m (263 lb·ft) of torque, compared to the 176 kW (236 hp) and 294 N·m (217 lb·ft) of the standard version. Other changes included a race-developed carbon fibre nose cone and rear spoiler, a carbon fibre 120 L fuel tank (as opposed to the 76 L tank in the standard car), a 4.3:1-ratio rear differential, 17-inch wheels, larger brake rotors and calipers. An improved Intercooler, Exhaust, and modified ECU were also included. Weight was reduced significantly with the aid of further carbon fibre usage including lightweight vented bonnet and Recaro seats to reduce weight to 1218 kg (from 1250 kg). It was a serious road-going race car that matched their rival Porsche 911 RS CS for the final year Mazda officially entered. The formula paid off when the RX-7 SP won the 1995 Eastern Creek 12 Hour, giving Mazda the winning 12hr trophy for a fourth straight year. The winning car also gained a podium finish at the international tarmac rally Targa Tasmania months later. A later special version, the Bathurst R, was released in 2001 to commemorate this, in Japan only. (26B & 20B ONLY!)





Toyota Supra Turbo vs. Lamborghini Gallardo
Disclaimer: All runs performed in Yugoslavia. Synopsis: Impromptu racing between a modded 2006 Lamborghini Gallardo and a modded Toyota Supra in the dangerous streets of Yugoslavia. Got a 25-80 pull, 45-130 pull, and a 45-110 pull. However, in the last two runs, I let the Supra spool before taking off. Mods and other information are below: Gallardo - catless Exhaust (LOC +Fabspeed combo) - 125 lb weight reduction - one passenger - 6 speed manual - approx. 450awhp Supra - Greddy T78 turbo @ 16 PSI - Supporting Modifications - 750cc Injectors - No passenger - Auto transmission - approx. 460rwhp Please subscribe if you enjoy cars, exotics, racing, and film-making. Please note: Since this was an impromptu race, I did not bring my HD camera or GoPro HeroHD setups. Therefore, only my intro scence is 1080P HD and the rest is crappy 640x480 iPhone 3GS footage rendered to 1080P HD. Subscribe and this race will go down again with a full camera setup and also the Supra getting more mods! Music - Custom Created in Sony Vegas Pro 9 using VideoCopilot's Pro Scores Software.
